Location: New Orleans, LA
Objective: Leaaf was contracted to assist the City of New Orleans, Capital Projects, with infrastructure improvements associated with the Broadmore Drainage Upgrades and Green Infrastructure Project. Sites consisted of the multiple public parks and playgrounds including AL Davis Playground, Clay Square/Burke Playground, Annunciation Square, Taylor Playground, and Van McMurray Playground.
Limited Phase I Environmental Site Assessment (ESA) Report – A limited Phase I ESA was performed on seven sites identified for green infrastructure projects. Historic and current recognized environmental conditions (RECs) were identified at each site to determine the environmental risk associated with redevelopment.
Phase I ESA Report – Reports for each site were produced outlining the following RECs: fill material from an unknown source at each site and varying evidence of adjoining gas stations, dry cleaners, automotive junk yard, and transportation facilities.
Phase II ESA – A Phase II ESA was performed on each of the seven sites identified. Soil and groundwater samples were collected from each site to further investigate the RECs identified in the Phase I ESAs. Soil and groundwater samples were analyzed for 8 Resource Conservation and Recovery Act (RCRA) metals; Polycyclic Aromatic Hydrocarbons (PAHs); Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX); hydrocarbon fractions; and dry cleaner specific volatile organic compounds (VOCs).
Phase II ESA Report – A report outlining the findings of the Phase II ESA investigation was produced for each of the seven sites. The data were evaluated in accordance with the Louisiana Department of Environmental Quality’s (LDEQs) Risk Evaluation/Corrective Action Program (RECAP). Concentrations of metals and PAHs in fill material were above the RECAP screening standard at all but one site.
